Katie Price has shared emotional videos of her son Junior defending his brother Harvey from a vile online troll.

The mature 10-year-old spoke passionately into the camera as he expressed his sadness that his disabled sibling had been mercilessly mocked in a sick tirade of abuse by a Twitter user.

In a series of three short videos posted on Tuesday night, Katie's son blasted the “disgusting comments”, as he said: “Do you know how heartbreaking it is? Imagine if your brother or sister is paralysed. Would you make fun of them?”

“It's just really hard because I love Harvey so much. Everyone who knows Harvey, he's such an innocent and loving boy,” he said.

In another video, Junior said: “He thinks he's got the guts to post what he said on social media. Let's see if he has the guts to apologise. Bet he can't do that.”

Fans of Katie and her family were quick to praise her children, as one said: “Well said junior you will make harvey proud that your sticking up for him well done junior x”

While another added: “Such a great kid!! He's growing into such a kind and intelligent young man, I can only imagine how proud Katie and Pete must feel to have him as their child. Well said Junior.”
